ISAAC SEARLS, OF NEWARK, NEW JERSEY.

MACHINERY FOR MAKING HAT-BODIES.

Specification of Letters Patent No. 11,910, dated November 7, 1854.

To all whom t may concern Be it known that LISAAC SEARLES, of Newark, in the county of Essex and State of which drawings constitute a part of said de-V scription.

Two difculties have hitherto attended the making of fine hat bodies by use of the common machines so that the mf'lfvetfacturers of ne fur hats have preferred making them by hand. The source of one difficulty has been in the picker, the picker teeth cannot be brought near enough to the bite of the feeding rolls, so but that the fur will have passed the line of contact before it reaches the teeth of the picking cylinder and consequently a part of the fur will be thrown upon the cone in tufts that will cause a knotty appearance on the surface of the hat. I have obviated this by using a brush feed roller, o-r cylinder furnished with bristles, see (B) in Figure 2 which shows an enlarged section of the feeding roll, this revolves against a metallic plate or bar (Z) which extends nearly down to the center of the roll terminating in a thin edge so that the picking cylinder (P) comes close up to it. It may be seen that the teeth of the picking cylinder strike within a twentieth ofl an inch ofthe roller and the fur is held and combed out straight before it is released from the shell, the object is to have the fibers all separated.

I am aware that rolls have been tried that were covered with card fillet-s, but if we set them near enough to-catch the fur they will hit the teeth and dull them. I have found the bristles to be much the best.

Another objection arises from using a single picker and throwing all the fur on one side of the cone, it is necessary to revolve the cone very fast, in order to lay the one direction makes it very diiiicult to work and very tender in the opposite direction. To remedy' this I have four pickers working on the four sides of the cone (0,) as indicated by the dotted lines on Fig. 1 which is a plan of the machine showing one picker and the airchest in which are the fans to exhaust the air from the cone. As all the pickers are alike it is only necessary to show one, and the dotted lines indicate the positions of the others.

Now by throwing the fur on all sides of the cone at once we are enabled to lay it equally over the surface without much motion of the co-ne and it is only necessary to revolve it very slowly, to guard against any little dierence that might be made by feeding one picker heavier than another. There is also another advantage in using four pickers, it enables us to spread the fur much thinner and to turn the roller slower so as to pick the fur a great deal more 4completely. and 4still perform more work in a given time. I also use a guide or movable board to direct the fur-as 4it comes'from the picker; see the guide (G) at Fig. 3 which figure is an isometrical view of the machine with one feeding frame (F,) and the air chamber (A) having the caps removed in order to show the cone (C) and the disk (D) on which it revolves; it may be observed that there is an opening through the disk communicating with the inside of the air chamber, this chamber is partitioned off into three apartments in two of which are the fans to draw the air from the cone as they need not differ from the common form and construction it may not be necessary to give any minute description of them or of the other parts of the picker, these things are in common use and are Well understood.

Fig. (4f) is an isometrical view of the case having a pane of glass in the top for the purpose of seeing the progress of the work andd regulating from time to timeby the gui e.

I do not claim these devices when used in the manner as heretofore used, and. for theyA What I claim as my invention and desire rections without depen-ding on the rotary to secure by Letters Patent ismotion of the cone to equa-112e the thickness. 10 1.
